BACKGROUND OF THE INVENTION

[0001] This application is a continuation-in-part of application Ser. No. 09/548,339 filed on Apr. 12, 2000, now pending.

[0002] 1. Field of the Invention

[0003] The present invention relates to a dust mopping, cleaning or a sweeping apparatus and in particular to mops or applications where debris is being removed by an apparatus. The present invention relates to a unitary flexible molded elastomer attachment that requires no assembly and allows for the floor dust mop to automatically rebound back after hitting obstacles. The new innovation allows for flexible floor dust mops to be less expensive to manufacture and to reduce an operator workload. In particular, the present invention relates to a flexible attachment device used in conjunction with an embedded or mechanical clamping mechanism for use with cleaning apparatuses or the like.

[0004] 2. Description of the Prior Art

[0005] The standard floor dust mop has two primary components. The first component is the floor dust mop head that comprises a rectangular structure usually made of a metal tube that supports therein a cloth covered sewn bag with a multiplicity of dust-absorbing cotton yarn-like strands. The support structure has a lateral cross bar which is used to attach the mop handle that is comprised of an assembled clamp mechanism consisting of springs and pivot rivets. The second primary component of the floor dust mop is the handle which is usually a cylindrical pole that is attached to a costly floor dust mop handle connector mechanism that requires assembly in order for the attachment to pivot in the transverse axis and allow the floor dust mop to move in multiple directions. The floor dust mop handle connector is removable and is typically fitted with a clamp that engages onto the floor dust mop frame. The floor dust mop handle connector is affixed to the top of the metal frame structure that supports the cotton skirt cover. The combination of the two permits the floor dust mop to be pushed and pulled by the exertion of a force on the handle and flex when coming in contact with obstacles.

[0006] One significant problem with flexible floor dust mops is the costly pivoting mechanism that allows the floor dust mop to flex around obstacles. Secondly, when the floor dust mop moves around an obstacle, the operator must twist the floor dust mop to regain the original position of the floor dust mop. Thirdly, the flexible mechanisms are made from steel and after being in use for a while they start to corrode or the spring on the release mechanism wears out.

[0007] Prior art has been patented on mechanisms or attachments that allow for a flexible joint between the floor dust mop head and floor dust mop handle. However, to date all prior arts are quite costly to manufacture due to the expense of springs and their installation into the floor dust mop head, e.g., U.S. Pat. No. 2,286,655 issued Jun. 16, 1942 to Frederick Supnick.

[0008] Therefore, a significant need exists to improve upon the previous patents that allows for a more cost effective flexible attachment to be made out of a single piece of elastomeric material, thereby eliminating costly mechanisms that require assembly and could corrode. It is also desirable to provide a flexible attachment that is economical to manufacture so that a floor dust mop that can flex back without operator movement when cleaning around comers, doorways and obstacles on the floor in order for it to be easily negotiated when it is necessary to sweep adjacent or around them.

[0009] It is highly desirable to have a very efficient and also very effective design and construction of a flexible attachment apparatus for use with dust mops or the like. It is desirable to provide a flexible attachment apparatus for use with dust mops, wherein a clamping mechanism is integrally connected to a flexible unitary molded body with the capability of automatically rebounding back the dust mop head after striking obstacles during use. It is also desirable to provide a flexible attachment apparatus for use with dust mops, wherein a clamping mechanism is mechanically attached to a flexible unitary molded body with the capability of automatically rebounding back the dust mop head after striking obstacles during use.

SUMMARY OF THE INVENTION

[0010] The present invention is a mechanism that is affixed at a location between a floor dust mop handle and a head of the floor dust mop to provide a flexible member at the junction where the handle is attached to the floor dust mop head. Through use of the flexible elastomeric member, when the floor dust mop head comes in contact with a stationary object, the floor dust mop will flex beyond 90 degrees deflection around the longitudinal axis in relation to the floor dust mop handle.

[0011] It is therefore an object of the present invention to provide an apparatus by which a conventional floor dust mop head can efficiently utilize a flexible elastomer floor dust mop handle attachment that can be economically manufactured.

[0012] It is a further object of the present invention to provide an insert that can be adapted to existing floor dust mop heads to provide flexibility.

[0013] It is an additional object of the present invention to provide an attachment which can be attached to the forward end of the floor dust mop handle to thereby provide the option of selling a handle with insert attached which can be affixed to the top of the head of a floor dust mop head.

[0014] Alternatively, the present invention is a flexible attachment apparatus for use with dust mops. The flexible attachment apparatus includes a clamping mechanism which is integrally connected to a flexible unitary molded body with the capability of automatically rebounding back the dust mop head after striking obstacles during use.

[0015] Still alternatively, the present invention is a flexible attachment apparatus for use with dust mops. The flexible attachment apparatus includes a clamping mechanism which is mechanically attached to a flexible unitary molded body with the capability of automatically rebounding back the dust mop head after striking obstacles during use.

[0016] Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0042] Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.

[0043] In the preferred embodiment, the insert member 10 in FIG. 1 is made of any flexible substance with memory such as rubber, urethane, nylon, plastic, titanium, and polyvinyl. It is also within the spirit and scope of the present invention for the attachment to be made of flexible but strong plastic such as MYLAR®, polypropylene or any other flexible material exhibiting the required characteristics.

[0044] Referring to FIG. 1, there is shown at 10 the present invention flexible floor dust mop handle attachment. The apparatus is made from an elastomeric material comprised of a one-piece unitary molded body. In the preferred embodiment, the flexible member 10 comprises a longitudinal section 14 and a lateral section 16 that are interconnected through a flexible connecting section 18 that is not limited to any shape or form, e.g., rectangular, oval, square, etc. when viewed looking down the longitudinal axis as depicted in the cross sectional view of FIG. 8. However, it should be noted that a rectangular shape is more economical due to the optimizing of the expensive elastomer material needed to produce the flexible member 18. A rectangular shape allows for the flexible member to flex around the lateral axis with less material needed to retain rigidity in the forward and aft movement when pushing and pulling the floor dust mop handle. In general appearance, the one piece molded insert looks similar to an extended Roman numeral I (when viewed from a front elevational view, see FIG. 1) with the top portion, item 130 being the receptacle to hold the floor dust mop handle 120. The floor dust mop handle is supported by the attachment body 14 that is a recessed cavity to hold the floor dust mop handle. Accordingly, the upper sleeve portion of the cylindrical sleeve section 130 includes an axial bore 140 having a uniform dimension so as to receive therein the transverse dimension of the handle 120. The thickness of the material encapsulating handle 120 is sufficient to not crack when impact to the head of the floor dust mop occurs. The upper sleeve section 130 has a diameter to tightly receive in a generally slip-fit relationship the transverse dimension of the handle to frictionally retain the handle therein. It will be appreciated that the handle is not limited to the slip-fit engagement. It is emphasized that while the slip-fit engagement is preferred, it is also within the spirit and scope of the present invention to utilize threaded means or attached means such as a bolt or rivet. The overall configuration of the flexible member 18 as it joins to the floor dust mop frame support clamp recess cavity 160 resembles an inverted “T” with the mid portion of the vertical leg being thin in the middle and the lower portion of the leg extending outboard in both the left and right lateral directions to form the clamp mechanism 16 as shown in FIG. 1. The clamp mechanism when attached to the floor dust mop frame 170 retains the floor dust mop head.

[0045] Referring to FIG. 2, there is illustrated in a perspective view the relationship between the floor dust mop frame and floor dust mop handle attachment. The floor dust mop support frame 161 is encapsulated by the clamp mechanism 16 and supported by the lateral recess cavity 160. The flexible member 18 adjoins the clamp mechanism 16.

[0046] Referring to FIG. 3, there is illustrated the clamp mechanism 16 and the protruding push lever 171 that allows leverage to open the jaws of the clamp.

[0047] Referring to FIG. 4, there is illustrated the movement of the flexible connector when in contact with a stationary object. The floor dust mop attachment is made of an elastomeric material member 18 which can flex over 90 degrees in relation to the floor dust mop handle support 14.

[0048] Referring to FIG. 5, there is illustrated the unitary elastomeric clamp mechanism. The clamp mechanism 16 has an upper jaw 152 and lower jaw 150 with an opening 170 that extends laterally. Opening 170 allows for access to cavity 160 that loosely supports the floor dust mop frame in order to pivot along the lateral axis. The upper clamp 152 remains rigid while the lower clamp 150 pivots around the lateral axis at 172. Protruded lever 171 when depressed displaces cavity 172 allowing for lower clamp 150 to move forward in relation to upper clamp 152 allowing for opening 170 to enlarge as shown in FIG. 6.

[0049] Referring to FIG. 6, there is illustrated the movement of the clamp mechanism between upper and lower clamps 152 and 150 when force is applied to the protruded lever 171 on side 174.

[0050] Referring to FIG. 7, there is an isometric illustration of the molded flexible attachment in its entirety.

[0051] Referring to FIG. 8, there is illustrated a cross sectional view with the flexible elastomeric material shaped as a rectangle shape. The purpose of a rectangular shape is to allow for maximum flexibility in the lateral movement yet retains rigidity in the forward and aft movement.

[0052] Referring to FIG. 9, there is shown an isometric illustration of an alternative embodiment of present invention molded flexible attachment without the protruding lever to ease in opening the clamp in its entirety.

[0053] This alternative embodiment is identical for attaching the base of the apparatus to a floor dust mop frame which is illustrated in FIG. 9. The alternative attachment is identical to the previous attachment described above except that there is no protruding lever 171. However, there is still the open recessed cavity 172 as depicted in FIG. 5 that allows for ease of installing the attachment onto the floor dust mop frame. To install the alternative embodiment, the operator must apply force to press on the attachment onto the floor dust mop frame.

[0054] Defined broadly, the present invention is a flexible unitary one piece molded floor dust mop to handle attachment to thereby provide a controlled flexible connection between the handle and head of the floor dust mop head to cause the floor dust mop head to move back and forth and the flexible insert being flexible.

[0055] Therefore, through use of the present invention, a flexible floor dust mop attachment can be manufactured that is economical, won't corrode and automatically rebounds back when striking a stationary obstacle.

[0056] Referring to FIGS. 10 and 11, alternatively there is shown at 210 the present invention flexible attachment apparatus for connecting a dust mop head 206 and a dust mop handle 209 together to form a dust mop (see FIG. 11). The attachment apparatus 210 comprises a flexible unitary molded body 212 which is made from elastomeric material and a dust mop metal clamping mechanism 250. The unitary molded body 212 comprises a longitudinal retaining handle section 214 which is integrally interconnected to a flexible connecting section 218.

[0057] It will be appreciated that the flexible connecting section 218 is not limited to a cross-section rectangular shaped configuration shown in FIG. 16. It is emphasized that while the rectangular shaped is preferred, it is also within the spirit and scope of the present invention to have a plurality of configurations such oval, round, square, etc. However, it should be noted that a rectangular shaped cross section of the flexible connecting section 218 is more economical when using the expensive elastomer material which is needed to produce the flexible unitary molded body 212. A rectangular shaped cross-section of the connecting section 218 allows the unitary molded body 212 to flex around the lateral axis with less material needed to retain and maintain rigidity in the forward and aft movements of the dust mop. In general, the attachment apparatus 210 has a generally spoon shaped configuration. The longitudinal retaining handle section 214 has a generally cylindrical shaped body with an axial central bore 240. The central bore 240 has a uniform inside diameter to receive therein the outside diameter of the dust mop handle 209, where one end of the handle 209 is press-fitted into the central bore 240 of the retaining handle section 214 and frictionally retained therein.

[0058] It will be appreciated that the handle is not limited to the press-fit engagement. It is emphasized that while the press-fit engagement is preferred, it is also within the spirit and scope of the present invention to have the handle threadedly engaged or attached by a bolt or rivet.

[0059] Referring to FIGS. 10, 11, 12, 14, 15 and 16, the clamping mechanism 250 may have several different configurations, thereby allowing a lateral support bar 261 of the dust mop head 206 to engage into the clamping mechanism 250. In this configuration, the clamping mechanism 250 has an upper clamp member 228 and a lower clamp plate 230. The lower clamp plate 230 extends upwardly and bends to form a U-shaped channel 285 (see FIG. 12) or any other shapes that allows the U-shaped channel 285 to be positioned into the flexible connecting section 218 and embedded therein with the flexible material to enclose the U-shaped channel 285 of the clamping mechanism 250.

[0060] The upper clamp member 228 is movably connected to the lower clamp plate 230 by a pivot rod 270 that extends through four aligned holes that are located on upper stationary pivot flanges 290 and lower stationary pivot flanges 242. The upper pivot flanges 290 are located on opposite sides of each other while the lower pivot flanges 242 are also located on opposite sides of each other as well. These pivot flanges 242 and 290 are used to support the pivot rod 270 which retains a spring-loaded coiled spring 280. The pivot rod 270 allows for the lower clamp plate 230 to pivot laterally in relation to the movable upper clamp member 228. The ends of the coiled spring 280 are preloaded and engaged with the upper clamp member 228 and the lower clamp plate 230, and allow for the movable clamp member 228 to stay in direct contact with the lower clamp plate 230 to retain the support bar 261. When pressure is applied to the upper clamp member 228, the clamp member 228 pivots around the pivot rod 270, thereby allowing the lower clamp plate 230 and the upper clamp member 228 to open the clamp flanges 260 in relation to flange 272. Once open, the support bar 261 can be released from or secured to the clamping mechanism 250.

[0061] Referring to FIG. 11, there is shown the perspective view of the present invention attachment apparatus connected between the frame 208 of the dust mop and the handle 209. The support bar 261 of the frame 208 is encapsulated by the clamping mechanism 250 as shown. The clamping mechanism 250 is embedded within the flexible connecting section 218.

[0062] Referring to FIG. 12, there is shown the upper clamp member 228 which retains the support bar 261 thereto. The clamp flanges 260 and the lower clamp plate 230 secure the support bar 261 thereto.

[0063] Referring to FIG. 13, there is shown the movement of the flexible connecting section 218 of the unitary molded body 212 of the attachment apparatus 210 when in contact with a stationary object (not shown). The unitary molded body is made of elastomeric material, where the connecting section 218 can flex over approximately 90° in relation to the clamping mechanism 250 and the retaining handle section 214.

[0064] Referring to FIG. 14, there is shown the U-shaped channel 285, where the U-shaped channel 285 is embedded within the connecting section 218 of the unitary molded body 212. The lower clamp pivot flanges 242 are attached to the lower clamp plate 230 by fastener means 248. The pivot rod 270 engages the upper pivot flanges 290 and the lower pivot flanges 242. The preloaded coiled spring 280 is wrapped around the pivot rod 270. The clamp flanges 260 and 270 form a cavity 234, where the support bar 261 is retained therein. When pressure is applied to the upper clamp member 228, the flange 272 is lifted upwardly as shown by arrow 252 to release or secure the support bar 261 of the frame 208 thereto. Flanges 260 assist in guiding the support bar 261 into the cavity 234.

[0065] Referring to FIGS. 17 and 18, still alternatively, there is shown at 310 the present invention flexible attachment apparatus for connecting a dust mop head 306 and a dust mop handle 309 together to form a dust mop (see FIG. 18). The attachment apparatus 310 comprises a flexible unitary molded body 312 which is made from elastomeric material and a dust mop metal clamping mechanism 350 which is mechanically fastened to one end of the unitary molded body 312. The flexible unitary molded body 312 comprises a longitudinal handle section 314 and a flexible connecting section 318 which is integrally molded with the handle section 314.

[0066] It will be appreciated that the flexible connecting section 318 is not limited to a cross-section rectangular shaped configuration shown in FIG. 23. It is emphasized that while the rectangular shaped is preferred, it is also within the spirit and scope of the present invention to have a plurality of configurations such oval, round, square, etc. However, it should be noted that a rectangular shaped cross section of the flexible connecting section 318 is more economical when using the expensive elastomer material which is needed to produce the flexible unitary molded body 312. A rectangular shaped cross-section of the connecting section 318 allows the unitary molded body 312 to flex around the lateral axis with less material needed to retain and maintain rigidity in the forward and aft movements of the dust mop. In general appearance, the attachment apparatus 310 has a general spoon shaped configuration appearance. The longitudinal retaining handle section 314 has a general cylindrical body with an axial central bore 340 having a uniform inside diameter to receive therein the outside diameter of the dust mop handle 309. One end of the handle 309 is press-fitted into the central bore 340 of the retaining handle section 314 and frictionally retained therein.

[0067] It will be appreciated that the handle is not limited to the press-fit engagement. It is emphasized that while the press-fit engagement is preferred, it is also within the spirit and scope of the present invention to have the handle threadedly engaged or attached by a bolt or rivet or other suitable means.

[0068] Referring to FIGS. 17 through 23, the clamping mechanism 350 can have several different configurations, thereby allowing the lateral support bar 361 of the frame 308 of the dust mop head 306 to engage into the clamping mechanism. In this configuration, the clamping mechanism 350 includes an upper clamp member 328 and a lower clamp plate 330. The lower clamp plate 330 extends upwardly to engage into the flexible connecting section 318 and fastened thereto by at least one fastener means 336 (two fastener means are shown). The at least one fastener means 336 can be rivets, screws, bolts or any other suitable means.

[0069] It will be appreciated that the method of attachment is not limited to the lower clamp plate inserted into the flexible connecting section 318 (as shown in FIG. 21) or attached on top of the flexible connecting section 318 (as shown in FIG. 24) or underneath the flexible connecting section 318 (not shown). It is emphasized that while the method of attachment shown in FIG. 21 is preferred, it is also within the spirit and scope of the present invention to utilize other means of attachment not shown herewith.

[0070] Referring to FIGS. 19, 21, 22 and 23, the upper clamp member 328 is movably connected to the lower clamp plate 330 by a pivot rod 370 that extends through four aligned holes located on upper stationary pivot flanges 390 and lower clamp pivot flanges 342. The upper flanges 390 are located on opposite sides of each other while the lower flanges 342 are also located on opposite sides of each other as well. These pivot flanges 342 and 390 are used to support the pivot rod 370 which retains a spring-loaded coiled spring 380. The pivot rod 370 allows for the lower clamp plate 330 to pivot laterally in relation to the movable upper clamp member 328. The ends of the coiled spring are preloaded and engaged with the upper clamp member 328 and the lower clamp plate 330, and allows for the movable clamp member 328 to stay in direct contact with the lower clamp plate 330 to retain the support bar 361. When pressure is applied to the movable clamp member 328, the clamp member 328 pivots around the pivot rod 370, thereby allowing the lower clamp plate 330 and the upper clamp member 328 to open the clamp flanges 360 in relation to flange 372. Once open, the mop support bar 361 can be attached or detached from the clamping mechanism 350.

[0071] Referring to FIG. 19, there is shown a bottom view of the upper clamp member 328 which retains the support bar 361 thereto. The clamp flanges 360 and the clamp plate 330 secure the support bar 361 thereto.

[0072] Referring to FIG. 20, there is shown the movement of the flexible connecting section 318 of the unitary molded body 312 of the attachment apparatus 310 when in contact with a stationary object. The unitary molded body 312 is made of elastomeric material, where the connecting section 318 can flex approximately over 90° in relation to the clamping mechanism 350 and the retaining handle section 314.

[0073] Referring to FIG. 21, the pivot flanges 342 are attached to the lower clamp plate 330 by fastener means 348. The pivot rod 370 engages the upper pivot flanges 390 and lower pivot flanges 342, where the coiled spring 380 is wrapped around on the pivot rod 370. The pivot flanges 360 and 370 form a cavity 334 which retains the support bar 361 (not shown) of the frame 308 of the mop head 306. When pressure is applied to the upper clamp member 328, the flanges 370 are lifted up as shown by arrow 352 to release or secure the support bar 361 of the frame 208 thereto. The flanges 260 assist in guiding the support bar 361 into the cavity 334.

[0074] Referring to FIG. 24, further alternatively, there is shown at 410 the present invention flexible attachment apparatus for connecting a dust mop head and a dust mop handle together to form a dust mop. In this embodiment, the flexible attachment apparatus 410 is very similar to the embodiment just discussed in FIGS. 17 through 23 and the only difference is how the clamping mechanism 450 is attached to the flexible connecting section 418. All of the parts of this embodiment of the present invention flexible attachment apparatus 410 are numbered correspondingly with 400 added to each number. Since it assembles and functions the same as previously described above except that the clamping mechanism 450 is attached on top of the flexible connecting section 418, the description thereof will not be repeated.

[0075] Defined broadly, the present invention is a flexible unitary one piece molded attachment that holds a handle and fastened to a clamp that retains a floor dust mop frame thereby providing a controlled flexible connection between the handle and head of the floor dust mop head to cause the floor dust mop head to move back and forth and the flexible insert being flexible.

[0076] The present invention is an attachment apparatus which includes a flexible unitary molded body that secures a handle at one end and a clamping mechanism which is integrally connected to the flexible unitary molded body for clamping a frame of a dust mop, thereby providing a controlled flexible connection between the handle and the head of the dust mop.

[0077] Therefore, through use of the present invention, a flexible attachment apparatus for use with a dust mop can be manufactured which is economical, won't corrode and automatically rebounds back when accidentally striking a stationary obstacle.

[0078] The attachment apparatus can be made from several materials. The manufacturing process which could accommodate the construction of the attachment apparatus may be injection, thermoform, etc. or other molding process. By way of example, the attachment apparatus can be made of any flexible substance with memory such as rubber, urethane, nylon, plastic, titanium, and polyvinyl.
